SWARTZBAUGH, OF SAME PLACE.

I FI'LT ERING-JOINT AND CUT-OFF.

SPECIFICATION forming part of Letters Patent No. 436,171, datedSeptember 9, 1890. Application filed June 10, 1890. Serial No. 354,959.(No model.)

To all whom it may concern.-

Be it known that I, EDWIN L. DETWILER, a citizen of the United States,residing at Dayton, in the county of Montgomery, State of Ohio, haveinvented certain new and useful Improvements in Filters, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

This invention relates to certain new and useful improvements'in filtersdesigned more especially for use for preventing the leaves, dirt, andother foreign substances from entering a cistern or other-receptaclethrough the leaders of the rain-water spout. It is designed to beaffixed in any suitable way to the side of the house or in any otherdesired position where it will have communication with the down-spout,and may be thus secured in any well-known way, such as by lugs andencircling bandsor any other provisions suited to the location.

The object of the invention is to provide a simple, cheap, and efficientdevice of this character by which the Water will be thoroughly filteredin its passage through the device, a series of screens of varying meshbeing provided and all made removable, suitable provisions being madefor the removal of the debris as it accumulates.

Other objects and advantages of the invention will appear in thefollowingdescription, and the novel features thereof will beparticularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawing, which,with the letters of reference marked thereon, forms a part of thisspecification, and which is a vertical section through my improvedfilter.

Referring now to the details of the drawing by letter, A designates achamber or receptacle of any suitable material-such as galvanized iron,tin, or other material suited to the purpose-and of any preferred form,preferably, however, cylindrical. It is divided horizontally by thepartition A.

O is an inlet-pipe extending through the top and also through saidpartition and rigidly held in place in any preferred manner. It isdesigned to receive or be connected with a down-spout, (not shown,) and,if desired, more than one inlet-pipe may be provided, so

as to receive the water from more than one down-spout or branches. Y I

D is a pipe extending through the partition A and through the bottom ofthe chamber A, extending,preferably, a short distance above saidpartition, as shown. This pipe is designed to be connected with or tolead to the cistern or other receptacle for the filtered water.

The horizontal partition A has a central opening to receive thefiltering devices. They consist of the basket-shaped receptacle E, ofsome reticulated medium, as wire-gauze of coarse mesh, and has extendingupward within the same the conical portion E of like mesh.

F is a conical. screen of reticulated mate rial of finer mesh than thatof E and E, and is carried by an encircling band F, substantiallyZ-shaped in cross-section, as shown in the drawing, he horizontalportion of which rests upon the partition A, surrounding the openingtherein, and is designed to thus support the filtering devices.

Secured to the cone F and arranged within the same near its base is theconvex cap or cover G, whose mesh is the same as that of the parts E andE. These parts E, E, F, and G are held together detachably bymeans ofthe vertical rod H, which passes through the apex of the two cones andat its upper end provided with a loop or handle h and at its lower endpassed through spider-arms h, attached to the base of the cone E, andbeneath the same receiving a nut h engaging the screw-threaded portionof said rod. These parts are thus held together, so as to all be removedtogether, if desired, but allowing of their ready separationfor-repairs, the replacing of any one part, or for any other purpose.

I is a cylinder of reticulated medium of very fine 1116811 removablyinserted within the upperchamber of the receptacle A, with its lower endfitted within and held by the vertical upper portion of the ring F. Itsurrounds the cone-F, and at its upper end is provided with astrengthening-band a.

J is a cover or cap fitted over an opening in the top of the receptacleA, and is provided with depending and annular flanges, as shown, to keepthe same in place and to steady the cylinder 1, as shown. It may belocked in place in any suitable manner.

In the bottom of the chamber A there is an outlet-aperture communicatingwith the discharge-neck b, and this aperture is normally closed by thevalve 0, carried by the rod (Z, which extends upwardly to the top of thechamber A, and near its upper end is provided with a notch 6, having aninclined approach, as shown in dotted lines, and adapted to engage astopfon the top of the chamber A and hold the valve elevated when it isdesired to remove the sediment from the chamber.

The operation is simple and will be readily understood. The receptacle Eis designed to be filled with charcoal or some analogous material, andas the water flows into the chamber A from the down-spout through thepipe 0 it first passes through the reticulated medium of the chamber Eand cone E 5 thence through the cap G, then the cone F, and finallythrough the fine screen I and out through the pipe D to the cistern orother receptacle. The course of the water is indicated by arrows. henthe valve 0 is raised, water may be admitted through the pipe 0 to Washthe sediment through the outlet 12. When the cistern is full, theraising of the valve cpermits the Water entering through the pipe C toflow off through the outlet 1) to the sewer or other place of deposit.

What I claim is- 1. The combinatiomwith the chamber having inlet andoutlet pipes and horizontal partition, of the reticulated receptaclebelow the partition with interior conical screen and the screens offiner mesh above the partition, substantially as specified.

2. The combination, with the chamber having inlet and outlet pipes andhorizontal partition, of the detachably-connected screens E, E, and F,the latter arranged above the partition and the two former below thepartition, and the reticulated cylinder I, of finer mesh, above thepartition and inclosing the screen F, substantially as specified.

3. The combination, with the chamber having horizontal partition andinlet and outlet pipes, of the connected screens E and F, of differentmesh, the cone E, extending within the screen E, the convex cap G withinthe cone F, and the reticulated cylinder 1, of finer mesh, surroundingthe cone F, substantially as specifiedi l. The combination, with thechamber having inlet and outlet pipes and valve controlled outlet, ofthe detachably-connected screen E and cone F, of different mesh, the

cone E within the screen E, the convex cap G within the cone F, near itsbase, the cylinder I, of finer mesh, inclosing the cone F, and the ringF, supporting all of said screens, substantially as shown and described.V

In testimony whereof I affix my signature in presence of two witnesses.
